Quality Wall
An additional control point
when your process needs reinforcing
A quality wall is a dedicated inspection point, placed in your flow for a defined period, that checks parts against agreed criteria before they move on. It adds a safeguard during a launch, after an incident or while a corrective action is being validated.

The challenge
Secure what leaves
your process
During a launch, after a customer complaint or while a new process settles, your standard controls may not be enough to stop defects from reaching the next step or your customer.
What we provide: a dedicated inspection station integrated into your flow, with checks targeted on the characteristics at risk, identification of checked parts and regular reporting of findings.
- Definition of the characteristics to check and the defect criteria
- Set-up of the inspection station in your flow
- Inspection of parts before they move to the next step
- Identification of checked parts and segregation of rejects
- Monitoring of defect trends and regular reporting
- Exit criteria agreed with you

Data to decide
when the wall can end
A quality wall is a temporary measure. The information it produces helps you judge whether your process is stable and when the reinforced control can be reduced or removed.
- Quantities checked and rejected per shift or per day
- Defect types, frequency and trends
- Identification of the parts and lots checked
- Escalation of significant findings as agreed
- Exit criteria reviewed with you

Frequently asked questions
When is a quality wall useful?
Typically during a product or process launch, after a customer complaint or an internal incident, or while a corrective action is being validated — whenever you need additional assurance that the parts leaving a step conform.
Where is the quality wall placed?
At the point in your flow agreed with you — often at the end of a line, before shipment or in a receiving area — depending on where the risk needs to be controlled.
How long does a quality wall stay in place?
It depends on the situation. Exit criteria, such as a period without defects on the characteristics at risk, are agreed with you at the start and reviewed against the data collected.
What is the difference with sorting?
Sorting deals with a suspect stock of parts that already exists. A quality wall checks the parts produced or received during a defined period, as an additional barrier in the flow.
What reporting do you provide?
Quantities checked and rejected, defect types and trends, and any significant findings, at the frequency agreed with you.
